With the same print engine as in the Interpret S405, you would expect very similar performance, and you'd be right. The same speeds of 16ppm and 10ppm for black and colour prints in normal print mode are just as unrealistic and we saw 3.9ppm rising to 6.78ppm on a 20-page, black text document.
The five-page black text and colour graphics test took 1:21, giving a speed of 3.7ppm. Compared with rival machines, these speeds are not bad and the machine is subjectively quite speedy when printing text pages. Not so, though, when printing duplex, as it has to wait six or seven seconds for ink drying between the front and reverse sides of each page. It printed a 20-side, 10-page document at an average speed of 3.61 sides per minute.
As with the Interpret, the copy interleaving on the Prevail is poor. While it does start printing each page before it has finished scanning the original, it doesn't start scanning the second and subsequent pages before the one before has finished printing. This is the main reason it took two minutes to copy a five-page document, which is slow.
The print quality, from Lexmark's new Vizix ink system, using separate cartridges for each colour and a directly etched, permanent head with a wider swathe, is an improvement on previous Lexmark offerings. Black text is clean and better formed than before and is getting closer to Canon and HP output.
Colour graphics are also reasonable and registration of black text over colour is good, though with some slight fuzzing of text characters. Colour copies still come through lighter than originals, in some places light enough to show the paper fibres through the print. Photo prints are improved, with better shadow detail and generally natural colours, which are more than satisfactory for day-to-day use.
The cost of cartridges is exactly the same as for the Interpret, giving print costs of 4.7p for an ISO black page and 11.83p for an ISO colour page, both including 0.7p for paper. As before, these costs look expensive in comparison with equivalent consumables from Canon and HP, but things may improve as more dealers start to discount - these are still very new machines.
For your extra money, compared with the Interpret, you get an extended warranty, high-capacity cartridges as standard, a full-colour LCD, a slow but useful duplex mode and more convenient paper handling. Print quality and running costs are no different from the cheaper series, but the Prevail Pro705 is still a reasonable all-in-one for SOHO office work.
